  通常,由氟化钾、硼化物及复杂的氟化物等组成”。如我国应用广泛的QJ102成分为35%B203-42%KF-23%KBF。钎焊时,熔点580C的B20,(硼酸酐)能与稳定性不很强的Cu.Zn、Ni和Fe等金属氧化物形成较易熔的硼酸盐;MeO+B203-→MeOB202]。但对稳定性很强的Cr氧化物,则主要靠氟化物与其反应:Cr203+6KF→2CrFs+3K20,反应生成物也能熔融于易熔的硼酸盐中被除去("。KBF(氟硼酸钾)熔点530C,熔化后分解为:KBF,-+KF+BF,析出的BF,(氟化硼)也具有很强的去氧化物的能力。母材及钎料表面的氧黑桃棋牌官网app化物的充分清除,为钎焊过程的顺利进行和获得牢固的钎焊接头提供了可靠保证。
